<h1>MSYS2</h1>
<h2>Software Distribution and Building Platform for Windows</h2>
</header>

<p><strong>MSYS2</strong> is a collection of tools and libraries providing you with an
easy-to-use environment for building, installing and running native Windows
software.</p>
<p>It consists of a command line terminal called
<a href="https://mintty.github.io/">mintty</a>, bash, version control systems like git and
subversion, tools like tar and awk and even build systems like autotools, all
based on a modified version of <a href="https://cygwin.com">Cygwin</a>. Despite some of
these central parts being based on Cygwin, the main focus of MSYS2 is to provide
a build environment for native Windows software and the Cygwin-using parts are
kept at a minimum. MSYS2 provides up-to-date native builds for GCC, mingw-w64,
CPython, CMake, Meson, OpenSSL, FFmpeg, Rust, Ruby, just to name a few.</p>
<p>To provide easy installation of packages and a way to keep them updated it
features a package management system called
<a href="https://wiki.archlinux.org/index.php/pacman">Pacman</a>, which should be familiar
to Arch Linux users. It brings many powerful features such as dependency
resolution and simple complete system upgrades, as well as straight-forward and
reproducible package building. Our package repository contains <a href="https://packages.msys2.org/base">more than 2000
pre-built packages</a> ready to install.</p>
<p>For more details see <a href="docs/what-is-msys2/">'What is MSYS2?'</a> which also
compares MSYS2 to other software distributions and development environments like
<a href="https://cygwin.com">Cygwin</a>,
<a href="https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux">WSL</a>,
<a href="https://chocolatey.org/">Chocolatey</a>, <a href="https://scoop.sh/">Scoop</a>, ... and <a href="docs/who-is-using-msys2/">'Who
Is Using MSYS2?'</a> to see which projects are using
MSYS2 and what for.</p>
<h2 id="installation">Installation</h2>
<ol>
<li>
<p>Download the installer: <a href="https://github.com/msys2/msys2-installer/releases/download/2021-07-25/msys2-x86_64-20210725.exe" class="button">msys2-x86_64-20210725.exe</a></p>

or <a href="https://github.com/msys2/msys2-installer/releases/download/2021-07-25/msys2-x86_64-20210725.exe.sig">GPG signature</a>

</li>
<li>
<p>Run the installer. MSYS2 requires 64 bit Windows 7 or newer.</p>
</li>
<li>
<p>Enter your desired <strong>Installation Folder</strong> (short ASCII-only path on a NTFS volume, no accents, no spaces, no symlinks, no subst or network drives, no FAT).</p>
<p><img alt="Second screen of MSYS2 installation" src="images/install-2-path.png" /></p>
</li>
<li>
<p>When done, tick <strong>Run MSYS2 now</strong>.</p>
<p><img alt="Third screen of MSYS2 installation" src="images/install-3-finish.png" /></p>
</li>
<li>
<p>Update the package database and base packages.  Unless your setup file is very recent, it will take two steps.  First run <code>pacman -Syu</code>:</p>
